It's not a law enforcement issue, it's a city planning issue.

The practical solution is to reallocate usage of the street to prioritize all modes of transport. i.e. Take a car lane and replace it with proper 2-way concrete barriered bike lane.

They're on the sidewalks because they don't feel safe riding in the street, and who would with huge trucks blowing past you at high rates of speed. But if you give them some infrastructure and someplace safe to ride, they won't be forced to dive through pedestrians on the sidewalk.

Or, they didn't know that they should be riding in the street. Which is a problem of both planning and enforcement.

The road the sidewalk paralleled is great (for the area) cycling infrastructure. 25 MPH, low traffic, sharrows, signed Bicycle Route, and with wide paved shoulders.

What I mentioned above was more likely out of ignorance than fear.
